Fixing dep build script on Windows and removing some warnings. Use bundled igl by default. Not building with the dependency scripts if not explicitly stated. This way, it will stay in Fix the libigl patch to include C source files in header only mode.

// Colon operator like matlab's colon operator. Enumerats values between low

// and hi with step step.
|
|
// Templates:
|
|
// L should be a eigen matrix primitive type like int or double
|
|
// S should be a eigen matrix primitive type like int or double
|
|
// H should be a eigen matrix primitive type like int or double
|
|
// T should be a eigen matrix primitive type like int or double
|
|
// Inputs:
|
|
// low starting value if step is valid then this is *always* the first
|
|
// element of I
|
|
// step step difference between sequential elements returned in I,
|
|
// remember this will be cast to template T at compile time. If low<hi
|
|
// then step must be positive. If low>hi then step must be negative.
|
|
// Otherwise I will be set to empty.
|
|
// hi ending value, if (hi-low)%step is zero then this will be the last
|
|
// element in I. If step is positive there will be no elements greater
|
|
// than hi, vice versa if hi<low
|
|

|

// I list of values from low to hi with step size step
