Fix reading arrays containing subnormal floating point values

[speth]

Changes proposed in this pull request

Use our fpValue function for converting strings to double for array inputs (of any dimensionality). We were already using this function for single floating point values, mainly because it provides better error messages for badly-formatted values. It turns out that it is also more robust for handling subnormal floating point values than whatever yaml-cpp does.
