Ideas for Jiffy PR

[AadumKhor]

What does this PR do?

With reference to #118 some of the changes that I find logical are added. isSame -> isSimilar since we are also taking into account the units which can be misleading in some cases. Equality operator is overloaded. Tests have been changed accordingly.

isJiffy and isDateTime removed. Functionality can be achieved using the is operator.

Types of changes

• [ ] Bug fix (non-breaking change which fixes an issue)
• [x] New feature (non-breaking change which adds functionality)
• [ ] Breaking change (a fix or feature that would cause existing functionality to change)

@AadumKhor and @calvintam236 It will be best if we could have three PRs for each of the three issues, for easy tracking and reviewing

1. Set the isJIffy and isDateTime to depreciated and update the usage of this function with the is operator
2. Adding the ==, >, <, >= and <= operators for the isSame, isAfter, isBefore, isSameOrBeforeandisSameOrAfter` functions respectively
3. Adding the isSimilar function

What if this PRs focuses on the first issue and create other two PRs for the remaining two
