A ReSharper Type Member Layout for C# that organizes the contents into logical regions.

<!--
I. Overall

I.1 Each pattern can have <Match>....</Match> element. For the given type declaration, the pattern with the match, evaluated to 'true' with the largest weight, will be used 
I.2 Each pattern consists of the sequence of <Entry>...</Entry> elements. Type member declarations are distributed between entries
I.3 If pattern has RemoveAllRegions="true" attribute, then all regions will be cleared prior to reordering. Otherwise, only auto-generated regions will be cleared
I.4 The contents of each entry is sorted by given keys (First key is primary,  next key is secondary, etc). Then the declarations are grouped and en-regioned by given property

II. Available match operands

Each operand may have Weight="..." attribute. This weight will be added to the match weight if the operand is evaluated to 'true'.
The default weight is 1

II.1 Boolean functions:
II.1.1 <And>....</And>
II.1.2 <Or>....</Or>
II.1.3 <Not>....</Not>

II.2 Operands
II.2.1 <Kind Is="..."/>. Kinds are: class, struct, interface, enum, delegate, type, constructor, destructor, property, indexer, method, operator, field, constant, event, member
II.2.2 <Name Is="..." [IgnoreCase="true/false"] />. The 'Is' attribute contains regular expression
II.2.3 <HasAttribute CLRName="..." [Inherit="true/false"] />. The 'CLRName' attribute contains regular expression
II.2.4 <Access Is="..."/>. The 'Is' values are: public, protected, internal, protected-internal, private
II.2.5 <Static/>
II.2.6 <Abstract/>
II.2.7 <Virtual/>
II.2.8 <Override/>
II.2.9 <Sealed/>
II.2.10 <Readonly/>
II.2.11 <ImplementsInterface CLRName="..."/>. The 'CLRName' attribute contains regular expression
II.2.12 <HandlesEvent />
