B4A Class [B4X] [Class] TextCrumbs v1 (BreadCrumbs using CharSequence)

This class helps you create a simple Clickable Text Based Bread Crumbs Feature which supports CharSequence too.

Usage is very simple.
Create a list which has individual items to be shown as bread crumbs. This can be text / charSequence or mix of both.
Initialize TextCrumbs and pass this list and a label where the crumbs are to be displayed.
Everytime you change the list, call refresh method.

Note: By default the label will be horizontally scrollable but somehow charsequence spans do not allow for dragging, so only way a person can scroll it is using separators. To make it easier for user, place your label in a HorizontalScrollView or any other way you like. Source Code is attached.
