More functions to Sets (What names we will use to it?)

[latot]

Hi, well, again with sets, this time i want write the proper functions to have it more functional, but i don't know exactly what names use in all cases, so here i'll list functions of it, and we can discuss if some function are necessary or not (its very probable i'll write this and then we can choose the names for it):

Reference: http://docs.sympy.org/dev/modules/sets.html

• boundary
• complement
• contains
• inf /Function collision, rename to infimum
• is_disjoint
• is_proper_subset
• is_proper_superset
• is_subset
• is_superset
• measure
• powerset /can be overloaded or use a new name? overloaded similar concept in octave
• productset
• sup /remane to supremum
• imageset
• is_left_unbounded
• is_right_unbounded
• left_open /rename to isleftopen
• right_open /rename to isrightopen
• is_Complement
• is_EmptySet /This can be added in 'isempty' function, or make a new func to be like isuniversalset?
• is_Intersection
• is_UniversalSet
• reduce /This can be added to simplify
• EmptySet /Added to new function domain
• UniversalSet /Added to new function domain
• Naturals /Added to new function domain
• Naturals0 /Added to new function domain
• Integers /Added to new function domain
• ComplexRegion
• a_interval
• b_interval
• polar /Function collision, rename to 'ispolar'
• psets
• sets
• normalize_theta_set
• domain
• list domains
• Range /rename to rangeset
• reversed (only in range)
• point

Remains update this docs of operators:
'-' in sets that means the difference of both, complement.
'+' union of two intervals
'*' its the ProductSet of two intervals

New function domain to get domains.

Before send a lots of pr with this, i think i'll wait to finish the current prs.
