Counts pushup currently from video input
##Working Based on angles calculates the direction of movement and contraints and when both directions have been checked the count increases.

##Errors and shortcomings
1.Hard coded angles : Difficult to be set up by non technical person.
Improvement might be automatic angle constraints checker
2.Angles based on single video: The angles have been taken from 2 videos
for left and right side push ups grown adults. If a child performs exercise erronous result is given.
3.No horizontal or vertical position checking: If a persons movements satisfy
the angle constraints no matter they are standing or doing it properly,
it would show as proper pushup.
