+/*! \brief Load a text file as a sequence of strings in memory.
+ *
+ * The configuration of the field expansion code in FORTRAN uses
+ * shared memory access and file I/O operations managed by different
+ * functions. Although this approach could be theoretically replicated,
+ * it is more convenient to handle input and output to distinct files
+ * using specific functions. load_file() helps in the task of handling
+ * input such as configuration files or text data structures that need
+ * to be loaded entirely. The function performs a line-by line scan of
+ * the input file and returns an array of strings that can be later
+ * parsed and ingested by the concerned code blocks. An optional pointer
+ * to integer allows the function to keep track of the number of file
+ * lines that were read, if needed.
+ *
+ * \param file_name: `string` The path of the file to be read.
+ * \param count: `int*` Pointer to an integer recording the number of
+ * read lines [OPTIONAL, default=NULL].
+ * \return array_lines `string*` An array of strings, one for each input
+ * file line.
