Biomedical-Imaging-Group/GlobalBioIm: v1.1 GPU functionality

v1.1 release notes The v1.1 release contains a new functionality for GPU computation plus incremental improvements and bug fixes. GPU functionality add the functions ones, zeros, useGPU, isGPU, gpuCpuConverter replace occurences of all() by sum( test)==0 replace occurences of ones() and zeros() by ones() and zeros() update the 3D deconvolution example with GPU add a page in the documentation dedicated to GPU Other changes fix a bug in OptiVMLMB compilation (you should recompile it by running installOptimPack.m) set saveXopt=false by default in OutputOpti add flag isSeparable for Cost classes. Generic implementation of applyProx_ for the sum of a separable cost with an indicator cost. add a direct prox computation for the composition of a CostL2 with a Downsampled Convolution add CostMixNorm21 a non negativity constrained version of CostMixNorm21 ADMM can now take a Sum of CostL2Composition in the F0 argument remove OutputOptiADM
