Added basic where logic to sequelize closes #321

[durango]

For more info:

#321

Basically allows us to do <, >, <=, >=, !=, between, and not between :)

Let me know if this is a suitable solution for you guys, we'll obviously need to write up documentation.

Looks pretty sweet! I wil have a proper look at the code later :)

Can it do multiple? As in combining for example lt and gt? If it does you might want to add a test for that

[durango]

@janmeier you definitely can, it'll be in order though I'll add a test to it though just to double check :)

[durango]

OK added :D

[sdepold]

ooh yeeah 👯

@durango Does that work for Date() aswell or only for strings?

[durango]

Note: Don't pull this in yet..

@gustavpursche not sure actually, I'll throw it as a test shortly :)

[durango]

OK, Date objects added, we look good to go :) Now onto better PRs

[gu-stav]

@durango Thanks a lot - very good work!
