Can't be used within md-dialog

[SimonSimCity]

Since this library uses the directive md-dialog to show the window to choose the date or time from, it's not possible to use it within a dialog. If I try so, my dialog is closed before the date-select or time-select dialog is opened.

If you want you can use my fork for now https://github.com/dpoetzsch/md-pickers. It has merged pull request #189 which should fix this issue. For details on the fork see #192.
