We were assuming only one basis vector when indexing the emulator
correlation strength.

This relied on the correct calculation of how many emulator correlation
strength parameters there were; we had assumed there was one svd term.

Again, this relied on the calculation of the number of emulator
correlation strength parameters.  We had assumed there was one svd basis
vector which is an incorrect assumption.

There are num_svd_terms of these things, not 1.

We were underestimating how many of these variables there were.  There
aren't always dimScenario+dimParameter.  There's
dimScenario+dimParameter *for each* emulator precision variable.
