[WIP] Added a more compact name and type lookup.

[BenjaminDev]

Description

Following the same pattern proposed by @alejandrosame here is a possible compact version for looking up name and type. Note it breaks with the bounded functions as it stamps out BoundedMeanInt and BoundedMeanDouble etc. But can be fixed if we adopt this approach.

@chinmayshah99 suggested that we make a numpy style api like #204
"What would be great is mention the datatype of the list in another argument,"

x.result([1,2,3,4], 'int') 

How do we want to address this as I think it's best done/explored early.
