Array method dumping ground

[eborden]

I'll come back and give these some more detail, just getting them off the top of my head before I forget.

Member methods

• join
• sum
• any
• all
• max
• min
• intersect
• reduce/fold
• map
• filter
• intersperse
• union
• difference
• intersect
• slice
• splice

Static methods

• repeat/fill
• map **
• filter **
• reduce/fold **

**repeat, but these methods can be very helpful with partial application and member methods don't provide this opportunity

Writing up tests for the remaining methods.

map/filter/reduce are not necessary as static elements with the details in #13
