This example creates an activation sequence for use in a forward problem.
The original activation sequence was created using a single region, tricubic Hermite
FEM mesh and solved for an Eikonal equation (refer PhD Thesis - K Tomlinson).
This activation sequence has been transformed, orthoganally projected onto
a 3 region BEM bi-linear mesh and fitted. This provides a smooth activation
sequence on a mesh with different geometric shape and properties.
The activation map can be visualised
