supportInfo mask

Creates a list of supported operators and types.
Each field of the array has the format: "x:name" where x is:
't' - type
'n' - null operator
'u' - unary operator
'b' - binary operator

'name' is operator/type name (in the case of operator, type of input operands is included).
''mask'' parameter can be an empty string, or one of field.
In this case, function returns an empty array, if operator is not included in the list.
Limited wildcard support is available. Type ''x'' may be replaced with ''*'', meaning all types.
For the ''mask'' partial match may be used, like ''abc*'', meaning any operators starting with 'abc' are reported, for example: *:name, t:*, t:name* or *:*
