removed references to and mentions of the replacement allocator

Potentially breaking changes are marked with an exclamation point '!' at the begin of their description.

* 2019-03-?? v4.0.0

 * Added the HTTensor class for Hierarchical Tensor Decompositions with balanced trees.

 * ! Removed support for the replacement allocator.

 * ! Changed some Makefile configs for more flexibility. See the new config.mk.default file and update your own config.

* 2017-05-31 v3.0.1

 * Added TTNetwork::use_dense_representations() to convert all components to dense representation.

 * Exporting Tensor::dense_copy() and Tensor::sparse_copy() to python.

# DEBUG += -D XERUS_TEST_COVERAGE           # Enable coverage tests

# Xerus uses many small objects (Indices, vectors of dimensions etc.) for which the standard allocator

# is not very efficient. With the following option, an experimental replacement allocator will be

# included in the library, which will _globally_ replace the 'new' and 'delete' operators in your program.

# Note also, that the replacement allocator is not (yet) thread safe!

# DEBUG += -D XERUS_REPLACE_ALLOCATOR

# You can add all kind of debuging options. In the following are some examples

DEBUG += -g                            # Adds debug symbols

# DEBUG += -D _GLIBCXX_ASSERTIONS        # Activate GLIBCXX assertions
