*
* class for creating matrix like timeframes for items *
* *
* this matrix is having the days of actual month in the x-axis and the *
* items, which could be projects, in the y-axis. *
* You will see a top-down view of all items and their associated *
* timeframes. You probably saw this in projectmanagement apps *
