The Euler angle vector (in radians) is converted to a rotation by doing the rotations around the 3 axes

a vector pointing along the X axis, first rotating it 3 degrees around the global Z axis, then rotating the resulting
vector 2 degrees around the global Y axis, and finally rotating that 1 degree around the global X axis.
*/
/* How we arrived at this llEuler2Rot
*
* Experiment in SL to determine conventions:
* llEuler2Rot()=<1,0,0,0>
* llEuler2Rot(<0,PI,0>)=<0,1,0,0>
* llEuler2Rot(<0,0,PI>)=<0,0,1,0>
*
* Important facts about Quaternions
* - multiplication is non-commutative (a*b != b*a)
* - http://en.wikipedia.org/wiki/Quaternion#Basis_multiplication
*
* Above SL experiment gives (c1,c2,c3,s1,s2,s3 as defined in our llEuler2Rot):
* Qx = c1+i*s1
* Qy = c2+j*s2;
* Qz = c3+k*s3;
*
* Rotations applied in order (from above) Z, Y, X
* Q = (Qz * Qy) * Qx
* ((c1+i*s1)*(c2+j*s2))*(c3+k*s3)
* (c1*c2+i*s1*c2+j*c1*s2+ij*s1*s2)*(c3+k*s3)
* (c1*c2+i*s1*c2+j*c1*s2+k*s1*s2)*(c3+k*s3)
* c1*c2*c3+i*s1*c2*c3+j*c1*s2*c3+k*s1*s2*c3+k*c1*c2*s3+ik*s1*c2*s3+jk*c1*s2*s3+kk*s1*s2*s3
* c1*c2*c3+i*s1*c2*c3+j*c1*s2*c3+k*s1*s2*c3+k*c1*c2*s3 -j*s1*c2*s3 +i*c1*s2*s3 -s1*s2*s3
* regroup: x=i*(s1*c2*c3+c1*s2*s3)
* y=j*(c1*s2*c3-s1*c2*s3)
* z=k*(s1*s2*c3+c1*c2*s3)
* s= c1*c2*c3-s1*s2*s3
*
* This implementation agrees with the functions found here:
* http://lslwiki.net/lslwiki/wakka.php?wakka=LibraryRotationFunctions
* And with the results in SL.
*
* It's also possible to calculate llEuler2Rot by direct multiplication of
* the Qz, Qy, and Qx vectors (as above - and done in the "accurate" function
* from the wiki).
* Apparently in some cases this is better from a numerical precision perspective?
