Description
@madeleineudell is the multiplication only implemented against shared arrays? Not sure if I am doing the wrong thing here:
```
using ParallelSparseMatMul
dimensions, components, samples = 180, 100, 1500
dictionary = shsprandn(dimensions, components, 0.1)
original_code = shsprandn(components, samples, 0.1)
data = dictionary * original_code
```
Returned error is:
```
julia> data = dictionary * original_code
ERROR: no method *(SharedSparseMatrixCSC{Float64,Int64}, SharedSparseMatrixCSC{Float64,Int64})
```

Research direction
Start from the shsprandn entry point and the multiplication expression in the issue, then locate the SharedSparseMatrixCSC multiplication methods. Reproduce the shown example and confirm that multiplying two SharedSparseMatrixCSC values completes without the reported missing-method error.
