getOptLambda: Get lambda.min and lambda.1se values
In cvwrapr: Tools for Cross Validation

Get lambda.min and lambda.1se values and indices.

1	getOptLambda(lambda, cvm, cvsd, type.measure)

`lambda`	The values of lambda used in the fits.
`cvm`	The mean cross-validated error: a vector of length 'length(lambda)'.
`cvsd`	Estimate of standard error of 'cvm'.
`type.measure`	Loss function used for CV.

A list with the following elements:

`lambda.min`	Value of 'lambda' that gives minimum 'cvm'.
`lambda.1se`	Largest value of 'lambda' such that the error is within 1 standard error of the minimum.
`index`	A one-column matrix with the indices of 'lambda.min' and 'lambda.1se' in the sequence of coefficients, fits etc.
