Calorie projection - for nutrition intake

Garmin calculates calories burned and display in the activity summary. For the advanced user, more data during the workout is useful. This complex data field allows you to see the current projection of how many calories you are burning per hour. It will also display an average. If you use the large 1-field version you will see a distribution over your entire workout of calories/hour. The 1-field version also display the total amount of calories you have burned so far during the activity (see pictures below). The field uses heart rate monitor. VO max is planned to be used when it is released in the SDK. The projection is based on weight, age, gender and current heart rate. Give me feedback: http://davidgutafsson.com 0.1.1.0 : Changed background color. Add restriction to not make projection under 65% of max HR.
