All classes with some AgoRapide specific attributes found in assembly ARCQuery

BinaryOperatorKey	Offers expressions with operators like +, -, * and /.
CompoundInvalidKey	Used as a practical solution in order to know that a given key has been attemped parsed, but was not valid.
CompoundKey	A class able to expand the concept of entity keys.
ConstantKey<T>	Represents a constant expression like "' '", "', '", "42".
EntityMethodKey	Key able to call read-only methods defined in the entity class with names like 'TryGet{FieldName}'.
Extensions
ForeignKey	Can find related values, through compound field names.
ForeignKey+EntityTypeAndKey	Describes an entity type and a key.
ForeignKey+ForeignKeySingleStep	Describes how to traverse between related entities.
ForeignKey+IKIPEqualityComparer	Used by TryGetPInternal when it needs distinct list of foreign entities, based on their keys
FunctionKey	Extracts data from an already existing value like extracting Year from a DateTime in 'Created.Year()'.
FunctionKeyAbs	Returns the absolute value of field, like 4 for '-4'.
FunctionKeyAggregate	Operates over a collection of properties.
FunctionKeyAggregateAvg	Calculates the average of the given properties.
FunctionKeyAggregateCount	Counts the number of properties found.
FunctionKeyAggregateDistinct	Returns a list of the distinct values of the given properties.
FunctionKeyAggregateJoin	Joins the given list of properties into a single property.
FunctionKeyAggregateMax	Calculates the maximum value of the given properties.
FunctionKeyAggregateMin	Calculates the minimum value of the given properties.
FunctionKeyAggregateSingle	Ensures that the given list of properties contains only a single item and returns that item.
FunctionKeyAggregateSum	Sums the given properties.
FunctionKeyDate	Formats a date without time component.
FunctionKeyDayOfWeek	Extracts DayOfWeek from field like 'Monday', 'Tuesday' and so on.
FunctionKeyDouble	Converts an integer to a double (decimal value).
FunctionKeyFirstLine	Extracts first line from string of text.
FunctionKeyHourMinute	Formats a timespan with only the hour and minute part. Uses format hh:mm.
FunctionKeyInt	Rounds a double value to the nearest integer (uses .NET data type Int64 (long)).
FunctionKeyLength	Returns length of (string) value of field, like 4 for 'John'.
FunctionKeyMonth	Extracts month component from field like '2020-12-09' becoming '12'.
FunctionKeyPercent	Multiplies the field value by 100 and adds a percentage sign.
FunctionKeyQuarter	Extracts quarter component from datetime field like '2020-12-09' becoming 'Q4'.
FunctionKeyShort	'Smart' way of showing time. Removes unnecessary information, for instance if date is the same as the current date then the date will not be shown at all. Trailing zeroes are also removed.
FunctionKeyTMB	TMB = Thousands, Millions, Billions.
FunctionKeyTotalHours	Converts a timespan to total hours (as an integer).
FunctionKeyTotalMinutes	Converts a timespan to total minutes (as an integer).
FunctionKeyType	Returns the type of a property.
FunctionKeyVeryShort	Returns the ToStringVeryShort representation of the given type.
FunctionKeyWeek	Extract week-number from field according to ISO 8601.
FunctionKeyYear	Extracts Year-component from field.
FunctionKeyYearMonth	Extracts Year + Month component from field like 2020-06.
FunctionKeyYearQuarter	Extracts Year + Quarter component from field like 2020Q1.
FunctionKeyYearWeek	Extract year and week number from field according to ISO 8601 like '2021-51'
MemberEntityKey	Can find value for entity which is member of entity being queried.
NewKey	A function creating new keys (new fields) that can be used against all object types in AgoRapide (against all entities).
NewKeyCountP	Returns the number of properties for a given entity object.
NewKeyCountPRec	Returns the number of properties for a given entity object.
NewKeyGetType	Returns the internal C# object type of the given object.
NewKeyToPropertyStream	Returns the PropertyStream representation of the given object.
OrdinaryKeyPlusFunctionOrQuantile	A CompoundKey containing some function keys or quantile key operating on an existing property of the entity in question.
QuantileKey	Can separate entities into quantiles, like Quartiles, Quintiles or Sextiles.
Query	Keeps track of progress of query, and the interim result.
QueryExpression	Represents part of a query (or actually a transformation) against a given collection and the data storage from which it was taken.
QueryExpressionAggregate	Aggregates over the given key.
QueryExpressionAll	Represents all entities for a given collection.
QueryExpressionCache	Describes if cache is to be used or not.
QueryExpressionComment	Allows insertion of SQL style comments (beginning with double hyphens / minus signs, '--') into queries.
QueryExpressionDataStorage	Experimental as of Mar 2022: Resets value for DataStorage
QueryExpressionHint	Describes if hints are to be generated (as query progresses) for potential new queries.
QueryExpressionLimit	Limits the final HTML presentation of results (limits the number of elements being presented).
QueryExpressionLog	A debugging tool used to extract detailed log information about the execution of the query.
QueryExpressionOrderBy	Orders collection.
QueryExpressionPivot	Creates a table by querying over two keys like
QueryExpressionRel	Enables 'jumping' or 'travelling' from a collection of one entity type to another (related) entity type.
QueryExpressionSelect	Selects which fields to include.
QueryExpressionSelect+Field
QueryExpressionSelfCreate	Returns self created collection from given class type.
QueryExpressionSelfCreate+ISelfCreateCollection	Provides a standardized mechanism for describing classes that are able to autogenerate collection of themeselves.
QueryExpressionShuffle	Shuffles collection in random order.
QueryExpressionSkip	Skips the specified number of elements from the current query result.
QueryExpressionStrict	Describes Strictness ON / OFF when executing query.
QueryExpressionSum	Specify for which fields to provide a sum.
QueryExpressionSum+Field	TODO: Consider if this class is necessary at all.
QueryExpressionTake	Takes a specific number of elements from the current query result.
QueryExpressionThenBy	Allows sorting by multiple columns.
QueryExpressionTitle	The title to be used in the final presentation of the query result.
QueryExpressionWhere	Executes a 'WHERE {key} {operator} {value}' against the given collection.
QueryExpressionWithSuggestions	Keeps track as each query item gets executed.
QueryProgress	Keeps track of execution of query (that is, a query consisting of multiple QueryExpression), and also stores final result.
Translations	Offers a very simple system for keeping track of translation between different ("western") languages.
TranslationsCollection	This would consist of one key per language, with keys like "de_DE", "fr_FR", "nb_NO".
