Add centralised methods for queries

[rwemay]

Description:

Matching some of the work done in Revit_Toolkit and now porting across to the BHoM/engine. Would be good then to tie this together with general data queries, so there is one query syntax across the framework represented in the UI. Queries should be able to be aggregated with logical AND/OR statements (like Revit_TK).

Just one example below. Also then querying numerical values greater than/less than (and concatenating for between).

FilterBy(string PropertyName, string PropertyValue, bool MatchCase, bool ExactMatch)
