[Feature] Provide an option for custom sorting logic in columns

[prdct-builder]

Hi TrinaGrid,

             Could you please provide an option to write our own custom logic for sorting the data on column header selection.

Hi @mazhar-sk
Could you please explain more

An example would be if we wanted to use "natural" sorting on fields with mixed text & numbers, as per the compareNatural function of the collection package. This particular one would be even better if it were available as a builtin ;-)

Edit: just realised you have provided the solution for this at: #104 - which is pretty tidy - thx!
