Use these date related top-level Kotlin functions to show sections like "Today", "Yesterday" and so on

Date header top-level Kotlin functions

There are several apps which show a list with sections like "Today", "Yesterday" and so on like (Inbox Android app)[https://lh3.googleusercontent.com/Oz13JGyH0H2XBd_sflttWnAK_LRafyHW_P59Wfc4kqasiAMLhHLyZgKBTz2MpwZbJg=h900-rw]

I wrote few top-level functions which are helpful to check if the date is upcoming, tomorrow, today, yesterday, this month, this week or older to show sections in (my app)[play.google.com/store/apps/details?id=com.bitfurther.notigo.student]

PS: I used (SectionedRecyclerView)[https://github.com/afollestad/sectioned-recyclerview] library to show sections in my app.
