Implement Mojo for item

[mehdishirazi]

Mojo is a feature that shows to project manager speed of resource time card.
Calculation:
HT = Total Hours
Total Number of days ---> DT = 1+ End date - Start date - nonwork days (weekends + holidays + vacation)
HM ---> Min hours per day for a nugget in a phase = HT / DT
HR ---> Sum of all hours reported
HL---> Hours Left = HT - HR
Reported days - DR
Days Left ---> DL = DT - DR
Regular Work Hours --->RH = 8 by default (should we make this an account setting?)

If HM > RH then we have an issue with the estimate. This should generate a warning during submitting estimates per Resource (or sub-resource)

Mojo (speed) color is:
Green by default, then set it to
Yellow if HL > DL * HM, or set it to
Red if HL > DL * HR
